In a first embodiment, the invention provides a battery pack including a housing. The housing includes an inner cavity, an interface for receiving a power tool, and drain holes on a base portion. Battery cells are positioned within the inner cavity. A first latch member and a second latch member extend through the housing and are operable to secure the battery pack to the power tool. The battery pack also includes electrical terminals electrically coupled to the battery cells and operable to interface with the power tool. A latch cover supports the first and second latch members. A first water discharge pathway extends along the latch cover, downward along a first space between the battery cells and the housing, to the drain holes such that the first water discharge pathway directs water infiltrating the battery pack to the drain holes.
In another embodiment, the invention provides a battery pack including a housing. The housing includes an inner cavity, an interface for receiving a power tool, and drain holes on a base portion. Battery cells are positioned within the inner cavity. A first latch member and a second latch member extend through the housing and are operable to secure the battery pack to the power tool. The battery pack also includes electrical terminals electrically coupled to the battery cells and operable to interface with the power tool. A terminal cover includes openings that receive the electrical terminals. A first water discharge pathway extends from the openings of the terminal cover, downward along a first space between the battery cells and the housing, to the drain holes such that the first water discharge pathway directs water infiltrating the battery pack to the drain holes.
In yet another embodiment, the invention provides a battery pack including a housing. The housing includes an inner cavity, an interface for receiving a power tool, and drain holes on a base portion. Battery cells are positioned within the inner cavity. A first latch member and a second latch member extend through the housing and are operable to secure the battery pack to the power tool.

The bottom wall 204 includes a plurality of apertures 200. The holes 196 and apertures 200 extend from the outer surface 216 of the battery pack 100 to the inner surface 218. The holes 196 and the apertures 200 are offset relative to one another. The holes 196 and apertures 200 may be created by extrusion or any other suitable manufacturing process. In the illustrated embodiment, there are eight holes 196 and six apertures 200; further embodiments may include fewer or more holes 196 and apertures 200.
The battery pack 100 also includes a bottom cover or overmold 138 illustrated in FIGS. 22-24 and 27-28 . The bottom cover 138 includes a body 302 having a bottom wall 304 integrally formed with four side walls 306-312 creating a cavity 314 therein. An upper boundary of the cavity 314 is defined by an edge 316 created by the four side walls 306-312. The bottom wall 304 defines a rectangular opening or cutout 305. The bottom cover 138 has an outer surface 318 and an inner surface 320. The outer surface 318 includes a plurality of recessed areas 322 that correspond to a plurality of projections 324 on the inner surface 320 of the bottom cover 138. The bottom cover 138 accommodates the insertion and removal of fasteners (not shown) via two through-holes 326 on a first end 328 and two recesses 330 on a second end 332. The bottom cover 138 also includes a plurality of holes or openings 194 that extend from the bottom wall 304 to the side walls 306-312.
